In Mobius, or.. as it seems: Green Hill Zone was as sunny and bright that always illuminated such a calming and beautiful atmosphere in the aesthetic of the world and land around mobians, but that was always temporary..

Dr. Eggman was committing another attack on Mobius in another failing attempt to rule over the world, again. If prison was certainly a thing, he would've been there for a lifetime, no explanation needed. Dr. Eggman sat in the cockpit of one of his gigantic robotic machines. It had the intentions of causing a massive amount of destruction to the shops and villages.

But you were stuck in the very beginning of this spree. Its giant mechanical foot was on its way to crush you into a fleshy pancake, until a blue blur was seen coming right at you at such a rapid rate, and then.. you were suddenly in a basement. Saved by being crushed by Dr. Eggman's robot.

"If you move.. that's on you." A tired yet cocky, jokingly voice was heard. It was Sonic. Sonic's head was seen above you, outside the basement, his gloved hands were holding the two giant double doors back from closing. Sonic seemed to appear off. But before you could say anything, he dashed out from whatever location he was in to stop Eggman once again, and the doors closed.

Leaving you in the dark.
